How to restart the AR service (back button issue)

By metalistik on Thu, 10/16/2014 - 01:32

Hello

I'm trying to create a simple "close" button for the overlay which pops up after a target has beer recognized. The issue I'm having is that when I use the close button I've created after let's say target A has been recognized, it won't recognise that same target again until Vuforia has recognized a different target (let's say  target B). Then and only then, when I return to target A, Vuforia will recognize it once again. I've tried cleaning the tracker ID, stopping and starting VuforiaAR service with little sucess. What can I do to make Vuforia recognise the same target twice in a row?

Thanks

Have you tried using the TargetFinder::clearTrackables() and updateSearchResults()  ?

See also the Cloud Reco or the Books sample code, where these functions are used.
